Aerospace giant Boeing has reportedly signed a deal with Iran Air to provide the Iranian flag carrier airline with plane parts. A regulatory filing which was issued on Wednesday reads that Boeing will provide goods and services "related to the safety of flight" for Iran's flag carrier airline, AFP reported.

According to the document, the aerospace giant will supply Iran Air with airplane parts, manuals, navigation charts and data under the terms of the accord.

The Chicago-based company also reported that it may sell similar equipment and services to Iran Air Tours which is a subsidiary of the Iranian airline.

Early in April, Boeing was granted permission by the US Treasury Department to sell plane parts to Iran following an interim nuclear deal between Tehran and six major world powers.

A Boeing spokesman said in April that the license covered the export of certain spare parts for commercial Boeing airplanes sold to Iran before the 1979 Islamic Revolution and did not allow sales of new aircraft to the Islamic Republic.

Boeing said the license was granted as part of the sanctions relief granted to Iran under the nuclear deal.

Reuters reported in February that two major US aerospace manufacturers, Boeing and General Electric, applied for export licenses in order to sell airliner parts to Iran following the interim nuclear agreement.

Iran and the five permanent members of the UN Security Council - the US, France, Britain, Russia and China - plus Germany sealed an interim deal on the Islamic Republic's nuclear energy program in Geneva, Switzerland, on November 23, 2013, for a six-month period. The deal, which took effect on January 20, expired on July 20.

The two sides agreed on the extension of talks until November 24 with a view to achieving a permanent deal that would end the decade-old dispute over Iran's nuclear energy program.

Under the deal, dubbed the Geneva Joint Plan of Action, the six countries undertook to provide Iran with some sanctions relief in exchange for Tehran agreeing to limit certain aspects of its nuclear activities.

In the past decade, Iran has witnessed several major air accidents blamed on its aging aircraft due to the US sanctions that prevent Iran from buying aircraft spare parts.
